CLOO is an iPhone app that allows people to rent their private bathrooms to their friends for a small fee (video). The app is a concept by Hillary Young and Deanna McDonald (it’s unclear if they actually plan to develop it).

CLOO’ is a community of registered users who choose to share their bathrooms and make city-living easier, while earning a small profit. Using social media connections, CLOO’ shows what friends you have in common with the host, turning a stranger’s loo into a friend of a friend’s loo.
